I too am trying to reuse an IE session but have no success with this:

use IeExisting;
my $ie = IeExisting->new( visible => 1, maximize => 1, warnings => 1);
$ie->gotoURL('http://www.google.com');
[download]

This starts up a new IE window rather than finding/connecting to existing session.

I confirmed it is using the IeExisting constructor (by commenting out the line with "->new" from IeExisting, but then I get an error "Could not start Internet Explorer Application through OLE" when trying to connect to an existing session

Or am I doing something wrong?

Suggestions and comments welcome.

I'm using IE7 on XP.

Change the error message to include $^E or Win32::OLE::LastError()

Many thanks for the suggestion - Here is the new error response.

If I start IE either with the original program or manually, then comment out the '->new' constructor in IeExisting like this:

    $self->{agent} = 
    Win32::OLE->GetActiveObject('InternetExplorer.Application')
    #|| Win32::OLE->new("InternetExplorer.Application")
    || die "Could not start Internet Explorer Application through OLE 
+$^E\n";
[download]

The response becomes:

Could not start Internet Explorer Application through OLE The requested lookup key was not found in any active activation context

If I don't comment it out it starts a new window with no error...

Hmmm...

IE version 7.0.5730.13 Build 75730
